Bishop to pursue Gillard over union links

Deputy Opposition Leader Julie Bishop has said Prime Minister Julia Gillard was "less than honest" when answering questions three months ago about her links to a union entity she helped to set up 17 years ago.

Ms Bishop said on Friday she intended to put "very detailed" questions to Ms Gillard during parliamentary question time next week about further information that has emerged since then.

Nick Styant-Browne, a former partner with Ms Gillard's former firm, Slater & Gordon, on Thursday raised questions about her connection to a mortgage on a property bought by her former boyfriend and Australian Workers Union (AWU) official, Bruce Wilson, in the early 1990s.

The purchase was allegedly partly funded with union monies from the AWU legal entity she had helped to establish.

The prime minister held a lengthy press conference in August to answer journalists' questions about the legal entity.

She has since referred to her answers that day when asked further questions about the affair and repeatedly denied any wrongdoing.

Ms Bishop said she began "looking forensically" into the information available after Ms Gillard's August 23 press conference.
